Preventing inhomogeneous elemental distribution and phase segregation in mixed pb-Sn inorganic perovskites via incorporating PbS quantum dots
文献摘要:
Inhomogeneous Pb/Sn elemental distribution and the resulted phase segregation in mixed Pb-Sn halide perovskites would result in energy disorder (band structure and phase distribution disorder),which greatly limits their photovoltaic performance.Here,PbS quantum dot has been synthesized and demon-strated as seeds for modulation crystallization dynamics of the mixed Pb-Sn inorganic perovskites,allow-ing an enhanced film quality and significantly suppressing phase segregation.With this additive power conversion efficiency of 8% and 6% is obtained under irradiation of full sunlight in planar and mesoporous structured solar cells in combination with CsPb0.5Sn0.5I2Br inorganic perovskite,respectively.Our finding reveals exploring the actual Pb/Sn atoms location in perovskite structure and its influence on developing efficient and stable low-bandgap perovskite solar cells.
